If you mean BSD-style process control -- yes, PS/2 and 370 AIX have it.

Which version of AIX was that RT running?  I am certain that the older
versions on AIX on RT did not have BSD process control.  I don't know about
the new RT AIX.

RT's AIX did not have any influences of Berkeley UNIX.  AIX PS/2 (and 370) is
4.3 compatible and you can expect to find in it almost everything that makes
4.3 BSD such a pleasure to use.  And because it's SVID compliant, it gives
you everything you expect to find in sVr2 (sorry, no streams).

>I thought that AIX was supposed to look alike on all platforms. 

Personally, I can't find a satisfactory explanation for IBM's desire to have
PS/2 and 370 UNIX ports compatible with RT.  It's like a tail wagging the dog
-- RT enjoyed some of the worst sales IBM ever had and had some of the worst
user community reception.  Why should such a commercial failure determine the
appearance of a perfectly sane operating system?
